"Every Gibson USA Les Paul between 1982 - 2007 is weight-relieved. They do not have solid-body construction. Weight-relief is also known as "swiss cheese holes" and refers to the nine holes drilled out of the body in order to reduce the weight of the guitar.Sep 18, 2010"

I think diamond knew the answer to that already. He was referring to the fact that weight relief is a modern phenomenon and that the Les Paul in its golden age never had it, or needed it. Gibson's use of heavy wood that needs to be weight relieved wood is often seen as a mark of its low quality, a callback to the Norlin boat anchors of the 70's.

And also pointing out, of course, that Tokai have never used weight relieved wood...

I guess it depends on how you look at it. at this point theyve been weight relieving the guitars for longer than they havent.

Theres been alot of great music made with these tools made from 82 on.

That being said, I own both "weighted" versions, and I cant hear any sonic differences between the two.
